Peak Frequencies

Spherical harmonic	Peak of $\left|{\tilde{A}}_{lm}\right|$	Related mode	Expected frequency
Y00	278	0f0	292
Y22	160	0f2	148
Y33	236	0f3	208
Y44	299	0f4	268
Y55	347	0f5	329

Notes: The spherical harmonics are listed in the first column. The peak frequencies (in N-body or gravitational units) of the amplitudes for each spherical harmonic are measured for the Be0 simulation shown in Figures 4, 5, and 6 using the spectra shown in the bottom panel of Figure 6. The simulation has an equatorial impact on the Bennu shape model. The measured frequencies are listed in the second column. The relevant normal mode frequency is shown in the third column in the form _nf_l. The expected frequency of this mode for the same simulation is listed in the fourth column. These frequencies are computed following section §2.2 (equations 8 and 11) for a homogenous isotropic elastic sphere with a Poisson ratio of ν =1/4 and P-wave speed of 712 in N-body units. The predicted and measured normal mode frequencies are similar implying that the mass-spring model simulations are behaving as expected.
